The mass center of the 3-lb ball has a velocity of (vG)1 = 6 ft>s when it strikes the end of the smooth 5-lb slender bar which is at rest. Determine the angular velocity of the bar about the z axis just after impact if e = 0.8.

Notes Week 2 LECTURE 3 Position vector from A to B = (Xb – Xa) i, (Ya – Yb)j, (Za – Zb)k STEPS TO FINDING FORCE VECTOR a. Find position vector along 2 points ^^^ b. Find the unit vector r(ab)/r(ab) c. Multiply the unit vector by the magnitude of the force EXAMPLE: r(ac) = (2i + 3j 6k)m and F = 420 N r(ac) = √2^2 + 3^2 + (6)^2 = 7m u(ac) = (2/7i + 3/7j + 6/7k) F(ac) = F(ac) * u(ac) F(ac) = (420N)* (2/7i + 3/7j 6/7k) F(ac) = (120i + 180j – 360k)N DOT PRODUCT The dot product of vectors A and B is defined as A ∙ B = ABcosϴ ϴ is always the smallest angle between A and B 1. The result of the dot product is a scalar 2. The units of the dot product is the product of the units of A and B **Basically asking how much of A lies in the axis of B or vice ver
